TSH95ID datasheet by STMicroelectronics

TSH95ID Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics provides a recommended PCB layout in the application note AN5343, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure optimal thermal performance.
• How do I select the correct output capacitor for the TSH95ID?
  The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. A general guideline is to use a low-ESR capacitor with a value between 10uF to 22uF. Refer to the application note AN5343 for more detailed guidance.
• What is the maximum allowed input voltage for the TSH95ID?
  Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the device.
• How do I implement overcurrent protection with the TSH95ID?
  The TSH95ID has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) between the output pin and the GND pin. The device will limit the output current to a safe value when the voltage across Rs exceeds 0.5V.
• What is the purpose of the EN pin, and how do I use it?
  The EN (Enable) pin is used to turn the device on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled. This pin can be used to implement power sequencing or to reduce power consumption in standby mode.
